SHOE-SUPPORT.

Specification of Letters Patent.

Patented Jan. 5,1915.

Application filed. July 26, 1912. Serial No. 711,677.

To all whom it may concern Be it known that I, RONALD F. MQFEELY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Shoe-Supports, of which the following description in connection w1th the accompanying drawings is a specification, like reference characters on the drawings indicating like parts for the several figures.

This invention relates to work supports for shoe machines and is herein shown by way of exemplification merely as embodied in a jack for a lasting machine of the hand method type.

In operating lasting machines of the type it has been usual for the work to be held by the hands of the operator to the operating parts of the machine. This labor, however, when Kept up for many hours in succession becomes fatiguing to the operator and furthermore considerable skill is required to position and hold the shoe in proper relation to the working parts of the machine.

The object of the present invention is to provide a jack of simple construction which will uphold the shoe in proper position to the machine so as to relieve the operator of the greater portion of the exertion of presenting the shoe and to enable him to gulde it more accurately and effectively for the operations of the machine, as well as to enable operators having little skill to operate the machine successfully.

The several features of the invention will be understood from the following description of the preferred embodiment thereof illustrated in the accompanying drawings;

Figure 1 is a side elevation in which some parts are broken away, a shoe being shown clamped in the jack; Fig. 2 is a perspectlve view, the shoe being removed, and Fig. 3 is a perspective view, showing the clamping members disconnected.

The work support comprises the shoe jack bed 2 having the usual heel pin 4 pivoted thereto at 6 and sustained at the rear by a spring-pressed stud 8. In the opposite end of the bed 2 is a slide 10 which is held in ad usted position on the bed 2 by a spring bolt 12.

A toe rest support 14 is mounted for movement vertically in the slide 10 and is normally upheld by a spring 16.

A toe rest 20 is pivoted to the upper end of the support 14 for limited movement about an axis extending longitudinally of the shoe.

Upon the inner face of the support 14 rack teeth are formed which mesh with a pinion 24 mounted in a split bearing in the slide 10.

To hold the shoe down upon the jack, fingers 30, 31 are provided which have fixed vertical positions and are arranged to slide freely, laterally of the shoe independently of each other and of the toe rest, in guides formed inthe two portions of the same split bearing which holds the pinion 24. The lingers 30, 31 are held normally separated by a spring 32. The spring 32 is passed through a sleeve 34 Which is provided with slots 36, 37 on its opposite sides. The slots are engaged respectively by pins 38, Fig. 3, in the slide portions 40, 41 of the fingers 30, 31 which are thereby held from excessive separation by the spring 32 which would otherwise force them entirely from the guides. The slides 40, 41 are held clamped in their guides by a clamping screw 42 which acts also at the same time to pinch the pinion 24 in its bearing and prevent its rotation. The sleeve 34 serves also as a bearing against which the slides 40, 41 are clamped when the screw 42 is tightened.

The bed portion 2 of the jack comprises wall portions separated sufficiently to admit the head 46 of the jack support and slides freely over the head, an anti-friction roll 48 being provided on the upper face of the head 46.

The head 46 is provided with projections 50 which are adapted to engage over a lug 51 provided between the walls of the bed 2 near its end. The jack is thus supported on the head 46. when it is near the end of the bed.

The head 46 is formed with a segmental slide 52 which slides in ways 54 formed in the swiveled head 56 of the jack post.

The head 56 of the jack post turns freely in a collar 58 which is pivoted at 60 to the forks 62 of the slide 64 which is adapted to work in and out between plane surfaces 66 formed on a bracket mounted upon the head of the machine.

The jack post 68 is supported by a spring 70 which is light enough to permit the jack and shoe to be readily moved up and down. The lower end of the jack post is supported in the ball joint 72 secured to the frame of the machine.

In the use of this mechanism a shoe is placed upon the last pin 4 and the toe portion is supported upon the toe pad 20 which is resiliently upheld by the spring 16. The shoe is forced downwardly against the tension of that spring until the fingers 30, 31 can be closed over the bottom of the shoe and last. While the fingers are thus held in place the screw 42 is operated and acts to clamp the slides 40, 41 and the pinion 24 at the same time in their bearings so that the forepart of the shoe is rigidly held above by the fingers 30, 31 and below by the toe rest 20, the vertical position of which is rigidly fixed by the clamping of the pinion 24. The shoe may now be slid longitudinally on the head 46, may be tipped laterally about an axis extending longitudinally of the shoe and substantially in the plane of the sole thereof on the segmental slide 52, may be rotated upon the swiveled head 56, may be raised and lowered by reason of the jack post being resiliently sup ported on the spring 70 and the jack post and jack mounted thereon may be swung toward and from the machine about the joint 72 by reason of the member 64 being guided between the faces 66 of the bracket on the machine.

I-Iaving described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A shoe support comprising a bed, a toe rest mounted for vertical movement relatively to the bed, clamping fingers adapted to engage over the edge of the shoe at the ball portion thereof, and means for simultaneously clamping the fingers in position over the shoe edge and the rest against downward movement.

2. A shoe support comprising a bed, a heel pin mounted on the bed, a toe rest slide adjustable longitudinally of said bed, a toe rest support mounted for Vertical movement onsaid slide and resiliently upheld, shoe bottom engaging means arranged to be positioned laterally of the shoe over the shoe bottom, and means for clamping the shoe bottom engaging means and the toe rest in their respective operative positions against the movements specified.

3. In a shoe jack, lateral clamps and a toe rest having relative movements horizontally and vertically to clamp a shoe forepart in the direction of its width and against depression respectively, and means responsive to a single manual control for locking said parts against either of said relative movements.

4. A shoe support comprising a normally yielding rest for the toe, side clamps, and.

means for locking the side clamps together and simultaneously locking the rest unyieldingly against depression.

5. A shoe support comprising a yielding rest for the toe, side clamps normally spring-pressed apart, a pinion, a rack on the toe rest engaging the pinion, and a locking device for securing the side clamps together and binding the pinion against turning, for the purpose stated.

6. A shoe support comprising a bed having a longitudinal guideway in its under face, a head adapted to enter said guidway and permit the bed to slide and to tip thereon, longitudinally of the shoe, and interlocking formations 011 the head and at the end of the guideway to limit the said tipping movement of the bed at the end of its sliding movement.

7. In a shoe jack the combination with supporting means, of fingers which have fixed vertical positions and are arranged to slide laterally of the shoe, a guide for the fingers formed as a split bearing, a movable toe rest, and means for closing the bearing to clamp the lingers in adjusted position and simultaneously to lock the toe rest.

8. In a shoe jack, a toe rest, a toe rest support, and side clamps mounted on the support for right line clamping movements and yieldingly held apart from each other.

9. In a shoe jack, a toe rest, a toe rest support, side clamps mounted on the support for right line clamping movements and yieldingly held apart from each other, and means to lock said clamps against relative outward movement.

10. In a shoe jack, a toe rest, a toe rest support, side clamps mounted on the support for right line clamping movements, connections permitting relative vertical movements of the toe rest and side clamps, and means to lock the clamps together and to lock the clamps and rest against relative vertical movement.

11. In an apparatus of the class described, a frame, a jack post pivoted at its lower end to the frame, and guiding and limiting connections between the upper portion of the post and the frame comprising a bracket projecting from the machine and having lateral confining faces, and a connector pivotally supported at a point vertically removed name to this specification in the presence of from said facefs and having one arm guided two subscribing Witnesses.
